More and more car owners are trying to maintain their vehicles by themselves. This results in significant savings because contemporary cars require more and more routine service and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that disturbs more and more Volkswagen Multivan owners is a clogged air flow meter, which will lead to a loss of power and black exhaust gases. In this article we are going to take a look at how to clean the mass air flow sensor of your Volkswagen Multivan? . First, we will explain how your mass airflow sensor operates and its value, second, why it might be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Volkswagen Multivan .

Utility and action of the mass air flow meter of a Volkswagen Multivan

.
So we begin our content with the procedure and goal of your Volkswagen Multivan flowmeter.

The goal of the mass air flow sensor on Volkswagen Multivan

The mass air flow sensor is a component that has been created quite recently and principally equipped on diesel models. In fact, with injection engines, the fuel and air intake has become very precise and it is so necessary for the ECU to know the exact volume of air injected into the engine to modify the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen Multivan, do not hesitate to consult our content on this subject.

Mass air flow sensor operation on Volkswagen Multivan

Now, we are going to take a look at how it operates, before trying to clean the mass air flow sensor of your Volkswagen Multivan , you must already find out how it functions to do this routine service action accurately.

The mass air flow sensor is consequently principally there to get statistics on the air intake of your motor vehicle. To get this done, it must be set up just after the air intake of your Volkswagen Multivan, i. e. just after the air filter. It is a pipe equipped with a sensor that will review the air in the intake and transmit the statistics to the ECU of your car.

Why clean the mass air flow sensor of a Volkswagen Multivan?

The mass air flow sensor of your Volkswagen Multivan can have problems and this is what we will try to discover and understand what problems you might be facing!

Mass air flow sensor problems Volkswagen Multivan

Here are the different problems that the air flow sensor of your Volkswagen Multivan can generate:

  • higher fuel consumption: Because a dirty flow meter will necessarily lead to higher fuel consumption due to poor air flow…
  • Power loss: Linked to similar issue, this lack of air can generate a loss of power to your engine.
  • Difficulties starting the car: Finally, one of the last classic problems connected with a dirty flowmeter will be that your Volkswagen Multivan will have more issues to begin the car.

How do I clean the mass air flow sensor from a Volkswagen Multivan?

After examining the operation and concerns that the flowmeter can generate, we will look at how to solve these problems by explaining to you how to clean the mass air flow sensor of your Volkswagen Multivan . You should know that this operation is quite very easy to carry out and you will not need advanced mechanical skills to do it yourself, a good technique to avoid a trip to the garage area and a steep bill. See below the different steps to stick to to carry out this routine service act:

  • After having located the mass air flow sensor of your Volkswagen Multivan , you will have to dismantle it. To get this done, action delicately, but you will just have to disassemble it on both sides of the air duct and detach the electrical plug on top of it.
  • Once disassembled, you will be able to continue to the step cleaning the mass air flow sensor of your Volkswagen Multivan . This sensor will, as time passes, get dirty and its two “filaments” that will give information to your computer on the quality and temperature of the air will no longer be able to collect data accurately, it is in this sense that it will affect the operation of the engine unit of your Volkswagen Multivan. The goal of this cleaning will be to take out all its impure substances to enable it to work efficiently again.
  • Let soak the lower section of your mass air flow sensor (not the plug part) in acetone or another solvent for a few minutes , which will take out most of the grime
  • .

  • Now we’ll move on to the very delicate cleaning of the flow meter filaments. You have to be very watchful, in any other case your mass air flow sensor will be permanently damaged. With the help of a fine brush and solvent, delicately clean the two filaments of your mass air flow sensor . If you are too afraid of harming it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.

Now you know how to clean the mass air flow sensor of your Volkswagen Multivan , you should feel a noticeable difference in the behavior of your engine unit.
